"The update to version 4 brings several interesting graphical and functional improvements. It's incredibly realistic; the horizon profile at your observation location allows for more precise calculations of star rises and sets. The 3D view has been significantly improved, with updated graphics for the well-rendered planets, and every astronomical event is faithfully reproduced. A full 5 stars for this beautiful app, an indispensable tool for both amateur and professional astronomers."
"If you're wondering which special objects are in the constellation you're looking at right now, and when they can best be observed, then this app is exactly right for you. I've tried just about every astronomy app out there. My conclusion: by far the most valuable app for amateur astronomers who want to explore the night sky themselves with their own telescope."
"This app is simply fantastic and keeps getting better. It offers a huge variety of features, making it the most professional app in the Play Store."
"Version 4 is amazing: intelligently programmed, very well organized. Thank you for this excellent work!"

The story behind Mobile Observatory
Creator of Mobile Observatory
Wolfgang Zima spent years as a professional astronomer before finding his way into software development. After completing his PhD in Astronomy at the University of Vienna, he worked as a postdoctoral researcher at the Institute for Astronomy at KU Leuven in Belgium for five years. It was there that he discovered a passion for scientific software — writing tools for analyzing spectra of pulsating stars and building a CCD image simulator for ESA's PLATO mission, a space telescope searching for Earth-like exoplanets.
Mobile Observatory started almost by accident: when his Nokia phone broke on a mountain biking trip in late 2010, Wolfgang got his first Android phone and was surprised that no good astronomy apps existed. So he built one. First released in January 2011, Mobile Observatory has since grown into one of the most comprehensive astronomy apps for Android and has been continuously improved for well over a decade.
Wolfgang lives in Freiburg, Germany, where he works as a Senior Mobile Developer at sevdesk. He continues to develop Mobile Observatory with the same enthusiasm as on day one — now with the help of modern AI tools that let him bring new features to life faster than ever.
